DEVICE FOR SELECTING AND SEPARAIING- HEDDLES.

Specification of Letters Patent.

Patented June so, 1914.

Application filed April 22, 1910. Serial No. 557,015.

To all whom it may concern:

Be it known that I, O'r'ro VON MEYENBURG, engineer, citizen of Switzerland, residing at Zurich, Switzerland, have invented certain new and useful Improvements in Devices for Selecting and Separating Heddles, of which the following is a specification.

This invention relates to an improvement in mechanism for selecting and separating heddles. Devices of this character may be used in connection with a warp thread drawing-in machine of the type disclosed by British Patent 3707 of February 14th, 1907. Machines of this type usually include as an essential feature thereof a device for successively separating the individual threads from a row of such threads, said device including a member movable against the row of threads to separate from the latter at predetermined intervals a thread and properly position the same to be drawn through the heddle. I of this kind forms the subject matter of my co-pending application for Letters Patent, Serial No. 557 014* filed April 22nd,1910. Machines of the type abovereferred to also include a device for threading the warp threads into and through the heddle eyes, combined with means to hold a warp thread which has been separated, in such position that it may be engaged by a hooked needle and drawn through the eye of the heddle which has been selected and separated from a series of heddles. A 'device of this kind forms the subject matter of my co-pending application for Letters Patent Serial No. 557016 filed April 22nd, 1910, while the present application relates to mechanism for holding the selected and separated heddle in readiness for drawing a warp thread separated by the first mentioned mechanism through the eye of this heddle by the second mentioned mechanism. The mechanism for selecting and separating heddles includes a fork acting as a heddle separating member, and means for reciprocating this fork and oscillating the same in a plane transverse to the heddles to be separated. This general type of mechanism is disclosed A separating device by the above mentioned British Patent 3707/07, and by U. S. Patent 461613.

The arrangement of parts accordingto the present invention is such that the ends of the fork are adapted to alternately act against the heddle shanks of the foremost row of heddles and move the row o'f heddles away from the one selected, so that the latter is free to be engaged by the detacher and is adapted to be moved, at a suitable time, into position for threading. One form of the invention is illustratively exemplified in the accompanying drawing, wherein Figure 1 is a front elevation; Fig. 2 a side elevation partly in section and with certain parts removed; and Fig. 3' a plan. I

In Fig. 2, A A A and'A" represent four heddle frames and lying on each bar thereof is a'second bar B wider'than the frame bar and serving to hold the heddle cords apart. .A frame work a carries four horizontal shaftsb parallel to each other, one for each of the, said heddle frames. Each shaft I) may be drivenfrom anothei shaft to by means of a gear wheel 0' and a wheel segment .9. At its left-hand end each shaft 1) is provided with a disk (2 having'at its extreme face a suitably shaped cam. A lever o is provided with a roller 6 which rests against this cam and a spring f draws the lever 6 toward the disk (Z, thus causing the roller 6 to move in conformity with the shape of the cam; this movement being transmitted to a shaft fwhich is capable of axial displacement in holes provided in the frame-work. is provided which may move along and around the shaft f, and to the fitting a fork g as Well as an arm 9 are attached, the end of the latter being capable of sliding in guiding grooves 2' 2' while the arms of the fork g are provided with projections 9 g directed inward (Fig. 2). Fitting g is also provided with a slotted extension 9 which together with the fitting g may move axially with the shaft f, but which may not rotate. The movement of shaft 1) is transmitted to a gear wheel m by means of gear A suitably shaped fitting Y shaft f and cari'yii'ig a pin 70 which pro jects into the slot of the extension 9 For every complete revolution of the shaft b the link Q makes half an oscillation which may be transmitted by means of springs p and to the beam 70. The latter however, is only rigidly connected with the fitting g by the parts 70 and as far as rotary motion is concerned. The beam 70 can therefore only follow the motion of the link when the fitting 9 and the arm have beenmoved sufiiciently far toward the left to allow the arm to pass the short rib i, lying between the two grooves 2' and '5 By means of spring g. a constant pull toward the right is maintained on the fitting The shaft f carries also between two collars a fitting 7L1 which in turn carries the detacher It. The fitting k is provided with a catch 7112; which may engage with the hookshapedglever whenever, as a result of the axial motion of shaft f, this is permitted. The lever has a right angular projection g ,which may come into contact with a collar 6 fixed on the shaft (2. The detacher it furnished with a projection 7L3 having a suitably shaped end. which rests against a bushing r fitted onthe shaft 5. The bush-- ing 7 is provided. with a cam T The detacher 7a! is kept inits normalposition by means of a spring Fi In course ofrotation of shaft 2) the projection 71, is forced. and for a time kept aside, whereupon the de- 1 tacher I moves toward the observer (Fig. 1).

1 Q Q2, and are hook-shaped members which serve to hold the heddles to one side after the heddle-eyeshave been threaded and by means of the detacher It the threaded heddles are positioned behind the hooks of these members The operation of the apparatus is as follows: Referring to Fig. 1 the device ismade to approach the gear from left to right, as shown by the arrow. The shaft Z) is made to revolve inthe direction shown. As a result of this motion the shaft f is moved aXially from left to right in a manner dependent upon the form of the cam on disk (Z under the action of spring f. As soon as thisaxial movement is suflicient for the catch ft? to be caught behind the lever g theshaft f is, by the same disk. (Z, caused to return to its previous position, of which clrcular movement around the shaft efiect of th s com ound movement of the detacher it is as fol ows: The heddle L on bemovement the fork g par-takes. The arm g finally reaches a position where it may move past the rib 6 At this instant the link 0 is in the position shown in Fig. it has the tendency to cause the fork g to move from right to left (Fig. 2). This will take place the moment the arm 9 passes from the groove 2' into the groove Upon further axial displacement of shaft f, the projection 57 strikes the collar N, the lever is re leased and fork g is caused to return to ts original posltlon under the actlon of the spring 9. The arm 9 is now in the groove 2' with the fork g inclined toward the left (Fig. 2) and as arm g ismade to move along the groove 6 theprojection 9' of the fork g catches the heddle L and forces it together with the adjoining heddles toward the right Fig, l). The heddle L is thus separated from, the others. The detachcr /t which in its normal position is in line with the heddles, not only moves within the space as defined in Fig. 1 by the two dotted positions, but as a result of the cam arrangement (1", r h describes at times a small f. The

ing isolated by the other heddles having been drawn toward the right (Fig. l) is taken charge of by detacher 72, whichwas made to swing over toward the left (Fig. 2)

on the projection 7L3 coming out of contact wlththe cam r andthen moves a short distance toward the left (Fig, l) and now, due

to the shape of the cam cl, the shaft f and therewith the detacher 7t, are allowed to come to a standstill for-a short time in order that the selected and separated heddle may be threaded. On the axial movement of the parts f and it toward the left (Fig. 1) being resumed, the detacher it together with the heddle L pass the hook on the hook-shaped member Q1 where heddle L is caught. The operation may be repeated for heddle L As for thefirst complete revolution of shaft 5 the gear wheel m has made only half a revolution; the link 0 is now in the position shown by dotted lines (Fig. 2), as a result of which the fork 9 takes up the position shown by dash-dotted lines. Thereupon the pro jection forces the heddle L aside, thus leaving the heddle L isolated. here it is desired to arrange for two or more of these devices, where therefore the heddles have to be threaded in succession, it will be found necessary to bring the working parts into motion successively. This may be done by fitting on the driving shaft. to one wheel segment 8 for each device. These wheel segments 8 are displaced 90 in'relation to each other. on the shaft to and are so dimensioned that each of them causes the respective wheel 0 on the appertaining shaft b'to make exactly one revolution. As soon as a Wheel segment leaves its wheel 0 a cam s which is also'fitted on the shaft w enters a slot across the face of the wheel 0, thus looking it.
